anv: enable VK_KHR_shader_float_controls and SPV_KHR_float_controls 

This adds support for
VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_FLOAT_CONTROLS_PROPERTIES_KHR and
enables de Vulkan and SPIR-V extensions.

Also, notice that this includes the updates applied to the
VkPhysicalDeviceFloatControlsPropertiesKHR structure in the extension
VK_KHR_shader_float_controls v4 and Vulkan 1.1.116.
